Exploratory drilling, such as in the oil, gas, and mining industries, has come to rely on the collection and transmission of many streams of real-time data to monitor and guide drilling. This has allowed safer, smarter, and more environmentally conscious drilling. As significant oil reserves become harder to find and reach, such data collection and transmission technologies become even... Read More

5687 – A Photodetector is a device that senses electromagnetic radiation, e.g., visible light, and generates instrument-readable electric signals. These devices have applications as sensors in aerospace/defense, oil and gas, utilities, construction, chemical industries, and the market for these devices was $292M in 2014 [1]. Key performance metrics for photodetectors are their responsivity, or the... Read More

6047 – Out-of-hospital sudden cardiac arrests affect more than 300,000 people in the United States every year. About 94% of all people who suffer from a sudden cardiac arrest do not survive. In the absence of treatment, every minute that passes after the onset of sudden cardiac arrest reduces the chances of survival by 7 to 10%. Jump-starting the heart using defibrillation and cardiopulmonary... Read More

6100 – A highly flexible and accurate beam-forming system for direct IF receivers that leverages continuous-time bandpass delta sigma modulators (CTBPDSMs) and bit-stream processing has been developed at the Electrical Engineering and Computer Science at the University of Michigan.
The aforementioned beam-forming system implements beam-forming in the oversampled bit-stream domain by directly... Read More

5934 – Researchers at the University of Michigan have developed an uncooled, highly sensitive infrared (IR) detector with an embedded bowtie nano-antenna. The performance of conventional IR detectors is limited by thermal noise. The sensitivity of these detectors is commonly improved by cooling them (cryogenic detectors). However, cooling of IR detectors entails high space and power requirements... Read More

A serially fed phased array with beam squint elimination has been developed by a research team in the electrical engineering and computer science department at the University of Michigan. Conventional military and commercial phased arrays use corporate feeding, in which the lines from the source to each antenna are equivalent, resulting in phase matching between antennae elements. This... Read More

5911 – Researchers at the University of Michigan have developed a protocol for the efficient over-the-air transmission of file blocks targeted towards low-power and battery-less embedded devices. Current protocols for transferring large data blocks to low-power devices (for example, during firmware updates) require a large number of acknowledgement frames, the transmission of which can consume large...
